The Blackhead Dilemma: COSRX BHA Liquid or LANBENA Pore Strip?

Blackheads are one of the most stubborn skin concerns, and two very different solutions keep coming up in every skincare conversation. On one side, you have chemical exfoliants like the COSRX BHA Blackhead Power Liquid. On the other hand, you have quick physical fixes like LANBENA Pore Strips.

More people are comparing these two options right now because social media has made both viral, but they work in completely different ways. Choosing the wrong one can leave sensitive or acne-prone skin red, irritated, or dealing with even more breakouts.

This guide breaks down both products honestly, using real ingredient science, so you can pick the best product for blackhead removal based on your actual skin type.

Quick Answer

If you want a gentle, long-term fix that treats blackheads at the root, COSRX BHA Blackhead Power Liquid is the better overall pick, especially for sensitive or acne-prone skin. If you just want a quick, visible fix before an event, LANBENA Pore Strips can be a fun occasional extra, but it doesn't prevent future blackheads the way a BHA liquid does.

What Is COSRX BHA Blackhead Power Liquid?

The COSRX BHA Blackhead Power Liquid is a leave-on chemical exfoliant from the popular Korean skincare brand COSRX. It's designed to dissolve the buildup inside pores rather than just removing what sits on the surface.

Its formula is built around Betaine Salicylate, a gentler, plant-derived form of BHA, paired with Willow Bark Water, a natural source of salicin that soothes skin while it exfoliates. Niacinamide is also included to help calm skin and support a more even tone over time.

This formula is generally made for oily, combination, and acne-prone skin types, though many people with mild sensitivity also tolerate it well when introduced slowly.

COSRX BHA Blackhead Power Liquid: How It Works on Deep Pores

Unlike surface-level products, BHA is oil-soluble. This means it can travel past the skin's oily surface layer and reach inside the pore lining itself.

Once inside, it breaks down the mix of dead skin cells, sebum, and debris that forms blackheads in the first place. This is why BHA salicylic acid benefits for pores go beyond simply removing what you can see.

Over time, consistent use can help pores appear smaller and less congested, because the root cause is being treated instead of just the visible tip.

What Is LANBENA Nose Plants Pore Strips – Blackhead Remover Cream?

The LANBENA Nose Plants Pore Strips Blackhead Remover Cream works completely differently. It's a peel-off mask-style product rather than a liquid exfoliant.

Its main ingredients are Polyvinyl Alcohol, which forms the peelable film, and Gelatin, which helps the mask harden and grip onto debris. Aloe Barbadensis (Aloe Vera) Extract is also added to soothe the skin once the strip is peeled off.

It's popular because it offers a visible, instant result. You apply it, let it dry, peel it off, and often see blackheads stuck to the strip immediately. This instant gratification is a big part of why LANBENA Pore Strips have such a strong following online. 

Ingredient & Method 

Which Is Better for Sensitive or Reactive Skin?

For sensitive or reactive skin, the COSRX BHA Blackhead Power Liquid is generally the gentler long-term option. Betaine Salicylate is milder than traditional salicylic acid, and Willow Bark Water adds a soothing effect.

Pore strips, however, physically pull on the skin as they're peeled off. This tugging action can weaken the skin barrier if used too often, and it may cause micro-tears in already fragile or reactive skin.

If you're searching for the best blackhead remover for sensitive skin, a liquid BHA formula that stays on rather than being ripped off tends to be the safer daily-adjacent choice.

Which Is Better for Acne-Prone/Oily Skin?

For oily and acne-prone skin, COSRX BHA again tends to offer more long-term value. Because it exfoliates inside the pore, it helps prevent new blackheads and clogged pores from forming, not just remove existing ones.

Pore strips can temporarily reduce oil and debris on the nose, but they don't address oil production or the buildup happening deeper in the pore. This makes them more of a spot-treatment than a true gentle exfoliant for oily/acne-prone skin.

Used together thoughtfully, though, both products can play a role, which we'll cover next.

Price & Value Comparison

LANBENA Pore Strips are usually cheaper upfront and sold in multi-packs, which makes the per-use cost seem low at first.

COSRX BHA Blackhead Power Liquid costs more per bottle, but one bottle lasts for weeks of regular use since only a small amount is needed per application. In terms of availability, both are widely stocked online and at most K-beauty retailers, though COSRX comes in a larger liquid bottle compared to LANBENA's small tubes or sachets.

Looking purely at cost per use, LANBENA works out cheaper for a single application, but COSRX proves more economical over months of regular use.

Can You Use Both COSRX and LANBENA Together?

Yes, many people in the COSRX vs pore strips debate actually end up using both — just not on the same day.

A safe combination approach looks like this:

1. Use COSRX BHA Blackhead Power Liquid 2–3 times per week as part of your regular routine
2. Reserve LANBENA Pore Strips for occasional use, no more than once every 1–2 weeks
3. Never apply a pore strip right after using BHA, since skin will be more sensitive
4. Always follow up with a moisturizer to support the skin barrier

This way, you get the deep pore benefits of BHA and the occasional satisfying "instant clean" from a pore strip, without overloading your skin.

Possible Side Effects or Precautions

Both products are generally safe, but they come with different risks. With COSRX BHA Blackhead Power Liquid, the main concern is over-exfoliation if it's used too frequently, which can lead to dryness or sensitivity, along with mild tingling on first use that usually fades with regular use.

With LANBENA Pore Strips, the main risks are skin stretching and micro-irritation from the peeling motion, plus temporary redness right after removal, especially with frequent use.

Always patch test any new product on a small area of skin first, and introduce it gradually rather than using it every day right away.

The Bottom Line: Which One Should You Choose?

If you want a proven, science-backed Korean skincare alternative for blackheads that works gradually and supports your skin barrier, COSRX BHA Blackhead Power Liquid is the stronger long-term choice.

If you want an occasional, satisfying instant fix before an event or photo, LANBENA Pore Strips can be a fun addition — just not your main strategy.

For most people dealing with ongoing blackheads, oily skin, or early acne concerns, combining a gentle BHA liquid for regular use with occasional pore strips offers the most balanced, skin-friendly approach.
